Walbro fuel pump mounting adapter for BMW E9X 335D

Custom made and used in my 550hp 335d.

This adapter will hold a Walbro 450L/h pump (maybe other flows too) in the intank bucket of an E92 335d (and probably other diesel models too).

It requires 4 M3 bolts and 4 corresponding nuts.

Outside diameter of the pump: ~39.5mm
Inside diameter of the OEM bracket the pump fits into: ~53mm
